Definitions
- the present invention generally relates to motor vehicle suspensions employing a transverse leaf spring acting as a resilient suspension member for a pair of wheels.
- the invention relates to the connection of such a transverse leaf spring to the structure of a motor vehicle and aims to provide a connecting device through which the ends of the leaf spring can advantageously be used as upper supports for the respective wheels in the manner of trailing arms.
- a connecting device characterised in that it comprises a pair of oscillating mountings disposed adjacent the ends of the transverse leaf spring and each including a pivot pin supported rotatably by the structure of the vehicle at right-angles to and above the spring and carrying on its lower part a fixing bracket for the spring and on its upper part a striking arm, and at least one stationary resilient stop fixed to the structure of the vehicle laterally of the striking arm of each mounting and against which the arm can oppose the translation of the spring relative to the median line of the vehicle by the effect of lateral loads on the suspension.
- the connecting device makes it possible to use the ends of the leaf spring as upper control arms for supporting the wheels, allowing the ends to oscillate and correspondingly to deform the free central portion of the spring between the two mountings without, however, exceeding the preset limits for relative vertical travel between wheels and vehicle structure.
- Both the connection of the pivot pin of the mounting to the bodywork and the connection between the fixing bracket and the mounting conveniently comprise respective shock-absorbing members.
- a part of a transverse leaf spring used in the suspension of a pair of wheels of a motor vehicle for example a pair of front steering wheels
- the respective references 2 and 3 schematically indicate the lower and upper joints of the support for the spindle of one of the wheels, which are aligned with one another about an axis 4 and of which the first is carried by a lower transversal oscillating arm, shown schematically at 5, and the second is carried by an end 6 of the leaf spring 1.
- the end 6 therefore functions at the same time as an upper control arm and, together with the remaining part of the leaf spring 1, as a resilient wheel-suspension member.
- the end 6 of the leaf spring 1 or upper control arm of the wheel is defined in relation to the rest of the leaf spring 1 by a mounting, generally indicated as 7, which, together with a specularly identical mounting adjacent the other end of the leaf spring 1, constitutes the device for connecting the spring to the structure of the vehicle, indicated 8.
- the mounting 7 includes a pivoting element in the form of a stirrup 9 through which the leaf spring 1 passes and which comprises two lateral walls 10 interconnected below the spring 1 by a transverse pin 11 and above the spring 1 by a striking plate 12.
- each support 14 comprises a sleeve of elastomeric material 15 and an outer annular retaining member 16 fixed to the structure 8 of the vehicle by respective screws 17.
- a bush 19 is mounted on the lower pin 11 with the interposition of a shock-absorbing sleeve of elastomeric material 18 and its upper part forms a flat bracket member 20 on which the spring 1 bears and is fixed, for example, by means of a pair of rivets 21.
- a stop buffer 22 of elastomeric material is fixed to the structure 8 of the vehicle in a position facing the abutment plate 12 of the stirrup member 9 on the inside of the latter, that is, on the side opposite the end 6 with the joint 3.
- the stirrup member 9 is free to pivot relative to the supporting structure 8 by the effect of deformations of the leaf spring 1 following the oscillations of the end 6 which, as stated, constitutes the control arm carrying the joint 3.
